llatented July d, t @il 3.,

To @ZZ zo/wm it may] concern le ity known that l, FRANK. A. Swanson, a citizen of the `United States, residing at Chicago, in the county of @ook and btate of Illinois, have invented a certain new and useful ln'iprovement in Vl/'indow-Screens, of whichv the following is a specilixation.

My invention relates to ii'i'ipi'ovements in Window screens and is illustrated diagraminatically in one form in the accompanying drawing, Wherein- Figure l shows an elevation; Fig. 2 a section along the line 2-2 of Fig. l; Fig. 5 a detail; Fig. el a section along the line 4me; Fig'. 5 a detail of the roller; Fig. C :i detail of the end ofthe screen and fastening meehanisin; Fig. 7 a section through the screen; Fig. S a` section along the line tlv-8 of Fig. 5; Fig. 9 a section along the line 99 of Fig. 5; Fig. l() a section showing a modified form of Fig. 8; Fig. ll a section along the line 11h11 of Fig. (3;'Fig- 12 a section along the line 12.*-12 of Fig. l: Fig. 13 a section along the line 13s-43 of'Fig. l; Fig. le a dei'elopn'ient of the containing box.

Like parts are indicated by the saine letter in all the figures.

The ivindoiv Caseii'ient- A eontainsi the upper sash A1 and lower sash A2 slidable therein in tlieiiisiial manner. The box A3 is removably held in the. easement in opposition to the sill A4 bi'y the screws Aj engaging the slot AN. .lhe spring roller Af is rotatably mounted in the box A3 and car'- ries the screen fabric AS, which is attached to the outside of the window sash A2 ad jacent its bottom. 'lhe slotted guides which are spread at the bottoni as indicated at A1 to form a. guide for the end of the screen as it leaves the roller and box, are attached to either end of lthe' easement outside of 'the window sash in such ina-nner that the selvage or edge A10 ofthe screen fabric, which is made of heavier o r more closely woven material, is held Within the slot and slides within the guide. The screen fabric is engaged along its upper edge by the. nietallic reinforcing member B, which is lient f upon itself, and about the vfabric to hold them in fixed relation one to thex other as indicated. This portion l is provided ivitli eyelets Bl, having the upwardly extending is contaiiied Within its holding slots B2 to engage the pins Bion the bottom of the. window sash., and carries the ont- Wardly projecting strip B which overlies the edge of the box fr* and prevents the entrance of Water and dust when the Win dow is in a. closed position and the screen g box. The part B is partially cut away as indicated in Fig'. 6, so that the strip B'i may slide in the space between the guides A10 but not interfere with them.

The roller Al is adjustable in length and has at either end the plugs G1 C2 provided with pins C11 C12 to engage the holding box, one of them round and rotating Within the box, the other rectangular and held against rotation therein. The rolleitselfiis made up o f two cylindrical portions C3 Ct of the saine cross sectional area -and shape indicated in Fig. SL ,They are made upiof sheet metal bent to a substantially circular form, the opposed edges being bent together as indicated in F ig. S to leave a fiat portion C5 overhung by a` tongue GG which is substantially parallel with it, the Whole within the peripheral line of the roller.

The roller section C3 carries an extension C30 rigidly attached theretovin slidable connection'ivith the roller section Ct Thisextension is provided with the channel CT iir which slides the junction portion of the roller section 0*. The screen A8 is provided at its lower end with the catch oi' clasp CS formed of thin sheet metal ben-t. upon itself as indicated to grip the free edge of the fabric. This clasp is provided with the tongue C10 which engages the tongue C to hold it upon 'the roller. The Clasp is bent as indicated` to conform substantially to the circular shape of the roller, so that when in position it forms with the roller a substantially cylindrical member about which the screen fabric may be wound.

The box A3 is provided at one end with the circular bearing D to engage one of the" pins C12 and at the other end With the ree? tangular bearing D1 to engage the other pin andv hold itagainstrotatiQn, thus per.-

niitting the spring D2 to retract t-he screen fabric as the tension upon it is released by y the descent of the window sash...

The box A3 is made as indicated in Fi .p

A, of sheet metal stamped in such manner that at either end are the' two lugs E E1. These lugs are separate one from the other, and when the roller is bent into the forni shown in Figs. l2 and 13, these lugs overlap one another and may be fastened together. The box A3 is made of two separate sections, one E2 having the inwardly turned edges, the other E3 having straight edges adapted to slide within the box and be engaged by the inwardly turned ,edgesY In the modified form shown in lFig. 10, o the metallic roller is not bent and interlocked into shape and position, but is soldered. The result, however, is substantiall the same in that there is a'ilat or depresse por: tion for the engagement of the screen carrying clasp, vthis portion being overlaid by a flange which engages and holds the clasp to the roller.

It will be evident that while I have shown in my drawings an operative device, still many changes might be made in size, shape and arrangement of parte without departing materially from the spirit of m vinvention and I wish, therefore, that my rawings be regarded as in a sense diagrammatic.

The use and operation of my invention are as follows: The protecting box is bent into position, the two sections, being slidably mounted one upon the other, are drawn out yuntil the box is of the same length as the width of the window. The roller sections are also adjusted to correspond in length with the box and are placed therein. The screen is then placed upon th'e roller, being held there by means of the removable clasp and wound about it. The roller is twisted until a slight amount of tension will be eX- erted by the-spring when the screen is in the rolled-up position and the over-hanging guard on the upper end of the screen overlaps the edge of the box. The box is then attached to t e window easement in such manner that it just clears' the lower sash. The guidesare then placed in position adjacent the easement in such manner that-they overhang the edge of the box. The screen is then drawn up into position, engaging the guides in such manner thatithe selvage edge is located between the parallel members of the guide. The upper` holding strip on the screen is then attached to the outside of the sash by means of pins, screws or other mechanism. The window is thenready for operation and may be opened or closed, and when it is opened, the screen will be drawn up, traveling between the guides and held in position. lV hen the window is closed, the

screen will be drawn ldown into the box where it will be protected from the weather.

It will be observed that the selvage on the screen is of considerable width and that the guides project a considerable width inwardly from the easement, thus giving a very considerable margin oi. adjustability. Since for a comparatively narrow window the screen would lit Adeep within the guides,

and for a comparatively wide window the screen would not titf'so far in, thus one width of screen be used for windows of considerable range of width. The same is true to an even larger extent with the housing box and the spring roller, since these are very readily adjustable in width to suit different widths of windows. The roller is made up of two similar roller sections of the same shape and cross-sectional area joined by a smaller section which .is rigidly attached to one of the outer sections and slidable on the other. The two outer sections are grooved as indicated whereby "a tongued clasp such as that indicated -to carry the screen may be held by insertion in the groove and may be easily withdrawn. It will be noted that the clasp ymay be inserted or withdrawn in a tangential direction and need4 not be drawn off of the roller by a longitudinal movement.

I havediscussed my device as if it were always to be applied to the lower sash of a window, but it will, of course, be evident that it is equally applicable to the upper sash, and to use it in connection with an upper sash it would be necessary only to attach the holding box to the upperlportion y guides projecting outwardly vabove Vsaid housing made up of two parallel strips one of which rests against the window sash and the other slightly removed Vfrom it and having a lower outwardly curved member overlying the upper edge of the housing said strip being perforate to attach it to the sash and having a reinforcing strip projecting Lo'fn'/Es (mtu-'m'dly away from the. sash adapted to travel between the two mnef edges o the guides and to merli@ the uppQr surface oi the hmmm j amd thcwil :md close the opemng' between l the housing I I ldow Sill an lower edge where 1t c the \\'111d w S111.
